Calculation of Integrated protection of electrical equipment

Abstract

The goal of this work is to develop a methodology for the integrated calculation of the protection of electrical equipment. A comprehensive calculation is a joint calculation of the earthing and protection system. Short circuits can provide a serious threat to human and animal life and health without a properly calculated and configured protection and grounding system. In addition to the physical damage, there may be economic losses to the company due to the need to repair equipment during short circuits. The solution of this problem is based on solving the following tasks: Analytical calculation of protection; Numerical calculation of protection; Proposal of integrated methodology of protection calculation of electrical equipment; Economic evaluation, allowing to estimate the profitability of protection. At the end of the paper, conclusions are made about the effectiveness of the developed methodology of complex calculation of the protection system and the economic and technical comparison of the two types of protections. The result of this work can be used for the solution of similar tasks.
